Message

At Moniepoint Microfinance Bank Limited, I built and scaled a referral reward system processing 10M+ daily transactions, with zero Kafka lag. I also developed reward distribution and campaign services for customer activities across the banking platform.

At MISPay, I’m developing backend microservices and built a Kafka and Go CDC pipeline for near-real-time data synchronization. My work spans PostgreSQL, MongoDB, Redis, Kubernetes, and GCP.

At Novaji Introserve, I helped build the FiberOne SMS gateway, which processed millions of daily SMS requests, and developed APIs for bulk SMS, OTP delivery, and transactional messaging. I’ve also worked on USSD applications and backend systems for financial and marketplace products.
